Explore the hidden secret codes of Samsung, HTC, LG, Sony, Oppo and other Android smartphones
If you are the endless tweakster type, then you will surely take an interest in your device's hidden codes. These system codes are entered using the dialer and exist mostly for device engineers to tinker with. The functionality they unlock relates to different component tests - display and antenna, for example - as well as toggling some obscure properties on and off. Usually, they are hidden for a good reason, which doesn't mean you can't make your phone run a little better, reset it quickly, or just get some kicks experimenting with stuff you aren't supposed to see unless you are in the know.

So, we've scouted some hidden codes for smartphones by Samsung, HTC, LG, Sony, Motorola, and Oppo. iPhones have hidden codes as well, but we'll be exploring these in a separate article. We've also included generic Android codes that should work on all recent Android devices. Have fun, but be careful - we take no responsibility if these don't work, or work in ways destructive to your phone! Be especially cautious with the factory reset - they don't ask around, they go straight to erasing all data on your device!

You forgot Sony's most important test *#*#7378423#*#* the Service Test Menu... you can test most of the phone from here instead of remembering the other codes...

HTC Info has a switch for Engineering Mode. What is it supposed to do? I'm not seeing a change.

Most of those doesn't work on my Note 3. IMEI is the only code that works and *#0*# which isn't listed above.

These codes are nice to know but why are they not part of an advanced menu to make using them more user friendly? The two things Android truly lacks is being user friendly and consistency across phones.

these are not really 'advanced' features that should be placed in an advanced menu. Most of these are used by service personnel when troubleshooting a phone for repairs/service etc...

Make sure you're using the stock dialer and not a downloaded one.
